Patented June 24, 1930 HARRY J. NELSON, or ELIZ B NEW JERSEY RAILWAY ROLLING STOCK Application filed February 16, 1928. Serial No. 254,738.

The subject-matter of the present invention is directed to improvements in'railway rolling stock adapted to receive a loaded container thereon.

The invention, among its features, contemplates certain improvements in the unitcontainer transportation system,where1n 1t is customary to load freight-receiving receptacles at a factory, or other point of manufacture, and deliver the same to a freight yard for transportation purposes.

Heretofore the containers have been packed for shipment at a factory as aforesaid, but the means for conveylng the same to the freight yard has not been constructed with special reference to the conditions ex sting thereat. In other words, the relative heightsof cars as compared with the trucks transporting said containers appear to have been neglected, and further the cars themselves have been constructed with little, f any, regard to the conditions existing in this unit transportation scheme.

Hence, the primary object of my inventlon is to provide novel and unique means whereby a loaded container may be conveniently and expeditiously loaded'onto a freight car for transportation to its delivery point.

Another object is the provision of a frelght car having its platform arranged with novel runways to facilitate the placement of a container, or containers, thereon.

With these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel formation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and par- 40 ticularly pointed out in the claims.

Tn said drawings:

Figure lis a side elevation of a freight car having a loading platform embodying my invention, one of the sides thereof being dropped to loading position to show the coincidence of certain cutaway portions and the ends of the runways.

Fig. 2 is a plan view thereof, illustrating the depressed runways and depicting the hinged sides in ordinary carrying position. Referring now in particular to the accompanying drawings, wherein like characters of reference denote similar parts throughout the several views, let 5 represent generally the type of railway rolling stock shown in Fig. 1, having the usual truck portions 6, diagrammatically illustrated in said figure, and platform 7 supported thereby. Rising vertically from said platform 7 are end walls 8 and 9, preferably fixed in position, while the opposite edges of said platform hingedly carry a plurality of sides 10, adapted to be dropped to the position noted for side 10 during the loading of said car. Disposed transversely of said platform are arranged a plurality of runways 11 which extend below the top surface of said platform, as indicated, and which coincide with the cutawayportions 12 of said sides 10 when the latter are in the let-down position indicated by 10*.

When a loaded container is to be placed onto the rolling stock just described, the sides 10 are let down to the position as indicated. The container-carrier is then positioned parallel with said rolling stock to bring the runways of the carrier and those of the former into alignment. By means of suitable skids, operating in the runways, the loaded container may be slid onto the platform 7 and finally the sides 10 are returned to an erect position, thus preventing the displacement of the container from the platform. Since the openings 12 in the sides 10 register with the runways 11, when said sides are in a let-down position, it is not necessary to bodily remove said sides as would be the case were ordinary car sides provided.

Having thus described my invention, '1 claim as new and desire to secure by U. S. Letters Patent:

1. Railway rolling stock comprising a plat form having a plurality of runways extending transversely thereof and disposed below the top surface of said platform and sides hingedly connected to lateral edges of said platform, said sides having openings adapted to register with the runways of said platform when in a let-down position.

2. Railway rolling stock comprising a platform having a plurality of runways extending transversely thereof and sides hingedly" connected to the lateral edges of said platform, said sides having openings adapted to register with the runways of said platform when in a let-down position.

In testimony whereof I affix my signature.

HARRY J. NELSON.
